I'd do your example as:
vec.d:
extern(C++,veclib){ struct … vec4 …; }
framework1.d:
import vec;
extern(C++,physics){ vec4 f(vec4 …) … }
framework2.d:
import vec;
extern(C++,graphics){ void g(vec4 …) … }
Yes, but that requires the authors of framework1 and framework2 to cooperate.
Not really. It is reasonable to expect that when Framework1 and Framework2 each
import 4th party Vec, that they do it with an import rather than inlining Vec's
declarations.
Which is why you with this DIP will end up with people being better off by using
pure C++ rather than mixed D/C++ from different sources.
With "graphics::g(physics::f(…))" this would not have been an issue.
Having an alternative lookup method is a large increase in language complexity.
